With the massive amounts of aftermarket parts available for muscle cars, it’s always great to get real-world reviews on highly-touted products. This is especially true for drivetrain components like crate engines, transmissions, and differentials because they can carry significant investment in both time and cost.
Tim Neil, the owner of this sinister black ’68 Charger, was so impressed with his Silver Sport Transmissions (SST) A41 4-speed overdrive automatic installation that he felt obliged to write the following glowing review:
Enclosed please find our new ’68 Dodge Charger Specifications Profile and note the addition of the SST A41 Automatic Overdrive Transmission. We also installed the Bergman small sector steering box with the BAC OEM direct fit coupler. We had to wait our turn at the shop but the installation was completed last week.
These two additions have moved the ’68 to a modern driving car without exception. No more dead zone in steering and your transmission has the big 493 purring at 65 MPH at 1750 RPM. What a joy to operate now! The SST A41 is simply outstanding, Sir ~ Well done. The weather will be great this weekend and I will drive the hell out of the old girl.
Very best regards,
As we’ve chronicled before, the A41 is the headliner of SST’s overdrive automatic kit that can jettison your Mopar’s driveline into the 21st century. With a 0.70:1 overdrive ratio, guys like Tim with big cubic inches are sure to appreciate the 30% drop in final drive ratio to help with fuel mileage. The advantage, of course, is that you don’t have to sacrifice any low-end performance in the first three gears since the fourth gear tacked on top for maximum cruising.
As the pictures show, installation is incredibly straightforward. The transmission tunnel doesn’t have to be cut and a standalone EZ-TCU controller is included in the kit. Even replacement cooler lines are included. We liked the trick modified factory console shifter that looks stock but is hiding a cable to shift the A41. Most probably wouldn’t even notice the change until that big wedge settles into cruising gear. Visit SST or give them a call at (865) 609-8187 to modernize your Mopar today.
